Lake Peigneur was swallowed by a whirlpool like in an anime, in a sad drilling that took away entire boats. The salt geologic bubble under the lake can absorb gigantic volumes of water, and a drilling for the exploitation of petrol initiated the hole.
> However, in May 2008, a new record for borehole length was established by the extended-reach drilling (ERD) well BD-04A, in the Al Shaheen oil field. It was drilled to 12,289 m (40,318 ft), with a record horizontal reach of 10,902 m (35,768 ft) in only 36 days.
[...] and below this lies some 7 km (4.3 mi) of sediment, placing the rift floor some 8–11 km (5.0–6.8 mi) below the surface, the deepest continental rift on Earth.
Nothing of great interest. That's a tiny scratch in the surface of the planet, less than 1% of the radius.
On the other hand although we lack the technology you'd need to destroy the damp rock where we live, we only live on some dry-ish outside surface parts of the rock, and we could trash that part and drive ourselves extinct. "Oops"
Also in both cases economic reasons. BP drilled to reach oil which makes economic sense, but AIUI the Russians wanted to keep drilling but eventually central government wouldn't give them any more money.
But yes, largely a coincidence. I think humans would see the same "pattern" if it were slightly more than 12km. We like patterns, we're the superstitious pigeon experiment but at a ludicrous scale. I would like to think the patterns I've seen point at some underlying more important truth - but the pigeon thought so too.
I ran the numbers on building the Deep Underground Command Center in my backyard at 1k meters, but it just doesn't pencil out when I add three S.H.E.I.L.D. helicarriers and their access tunnel.
There's also one under Yerevan, Arnenia. Funnily, the altitude differences in the city are so large that the bottom of the mine is still higher above sea level than the city center.

The Wikipedia page on borehole doesn’t mention Deep Water Horizon at all.

Also, I knew Baikal lake was deep, but not how deep its sediment layer is! That looks like something out of a Lovecraft story...
